BASIC FUNCTIONALITY
Switching system modePress the mode button (see buttons and icons) to switch between all available system mode settings. When the mode is “Off” the thermostat will not bring on your heating or cooling systems.
Fan modeIf you want to circulate the indoor blower, you can switch fan mode to “On.” Turn the fan back to “Auto” when you want the thermostat to control your indoor blower as necessary. Leaving the fan in “On” will run your blower continuously.
Holding one temperatureIf you want to hold one temperature, turn Schedule “Off.” Then, adjust the set point using the up and down arrow buttons. The thermostat will hold this temperature, in the set system mode, until you turn Schedule back “On” or until you adjust the set point again using the up and down arrow buttons.
Temporary holdWhen your Schedule is “On,” your Sensi thermostat controls your home based on the time and temperature settings in the current schedule. To temporarily change your temperature, use the up and down arrows in the app or on the thermostat. Your Sensi thermostat will display the time it will hold for next to the set temperature. It will hold your new temperature until the next scheduled set point with a minimum hold time of two hours.

Does wire color correspond to the thermostat terminals?
Wire color does not always correspond to the thermostat letters. A white wire may be attached to the “W” terminal on the old thermostat, or it may be attached to a different terminal with a different letter. Be sure to take a photo of the old thermostat that shows the wire colors and terminal letters before labeling and removing any wires.
